Are you a video store junkie? If so, you need to see "Rewind This!," a retrospective on the impact of home video on the world of cinema and on society as a whole. Once upon a time, home video did not exist. When it came, though, home video gave us the rewind button. It gave us the possibility of taping our favorite TV shows. It let millions of small children watch the same movies thousands of times in a row. And it gave us boatloads of obscure, direct-to-video trash, sleaze, and fringe titles! And then there is the box art, the lovely, lovely box art (often better than the movie itself), to which, of course, the cover of "Rewind This!" plays an obvious and spot-on tribute.If you see only one movie this year, this movie is probably not for you. But if you have spent literally years of your life trawling through video store aisles, seeing it is a must. It is a massive bear hug to everything that was made better by the advent of home video.
